Hello, gager23!

Arrange the odd numbers from 9 to 25 in a magic circle

so that the sum of the numbers in each straight line is the same.

There is one circle inthe middle and 8 around it. There really isn't any formula for this, but there is a **very** logical procedure.

Isn't it reasonable to put the *middle* number in the center of the circle?

Next, take pairs of numbers "from each end": .

. . Note that the pairs have the same sum: 34.

Place the pairs on opposite ends of a diameter.

Then one possible solution looks like this: Code:

* 9 *
* | *
19 | 11
* \ | / *
\ | /
* \ | / *
21 - - - -17 - - - - 13
* / | \ *
/ | \
* / | \ *
23 | 15
* | *
*25 *
